Akira, having managed to overcome the vampire lords' assassins, reaching where Mina and the lords are before the deadline of their bet (the lords were wagering among themselves which of their assassins could kill Mina's "dog" and return first). Having expected Akira to die (not surprising since they hate werewolves) the looks on their faces are priceless. Even better, the one that gave Mina the "chastity test" ends up dusted after foolishly trying to rush Akira. And of course the salute of the wolf corps as they take Akira to be treated.
In volume 11, Yuki is the only one who knows that Mina has been replaced by an imposter, and she is half-crippled, confined to a wheelchair, and mute. All her electronic communications are being intercepted, and it seems like she has no options but to just watch in horror as the monster who's replaced her friend tricks everyone around her, making them dance to her tune. Instead, Yuki risks killing herself, suffering further critical injuries, to force the false Mina to allow Akira to see her. And when he does come, she manages to secretly pass her message on to him despite still being mute and immobilized and monitored from every possible direction. A single crippled, brain-damaged human girl manages to outsmart the most dangerous puppetmaster in the series, and set in motion the events that lead to that puppetmaster's downfall.
The rescue of Mina in volume 12. All of it. The best part being when Akira and Mina are escaping, and Rozenmann and his men can only watch from the window. Mina smiles at him, then flips him off.
In Volume 13, Lords Scott, Antonio, Ernest, Edward and Connery make a stand to rescue Mina and Akira from Rozenmann's army, laying down their lives. All of them die with smiles on their faces, having devastated Rozenmann's army, rescued their lady and even destroyed Rozenmann's pride and arrogance, taking his castle with them. Mina's tribute to them is to cut her hair and release the strands into sunlight, creating trails of fire to honor her guard. It'd be a tearjerker if it wasn't just so damn badass.
In volume 14: We have the Beowulfs arrive to help a family of fangless who were being harbored by their human friends. There was an angry mob led by Takeda there, and he shoots first: thus giving the werewolves the OK to transform and kick all their asses without getting injured. One of them then gives the most delicious "The Reason You Suck" Speech ever:
